JACKSONVILLE, Fla — Two people are facing charges connected to an Oct. 6 fatal double shooting of an Uber driver and his passenger near the 7400 block of Kylan Drive West.
22-year-old Ju'Quan Mills is charged with two counts of second-degree murder and 23-year-old Diamond M'Kayla Harris is charged with accessory after the fact.
Earlier this month, First Coast News identified both victims as Antonio Tillie Jr., 19, and Bryant Grund, 31. Tillie, the passenger, was the target, and Grund, the Uber driver, was an innocent bystander, First Coast News has learned.
An arrest report states the shooting was gang-related and both suspects confessed to their involvement.
On the day of the shooting, the Jacksonville Sheriff’s Office was dispatched to 7440 Kylan Drive West for reported gunshots. When officers arrived, they located a Mini Cooper Clubvan that had crashed into a home.
Grund was found in the driver's seat and Tillie was in the backseat. Both were suffering from multiple gunshot wounds and were pronounced dead on the scene.
Through interviews investigators discovered the victim (Tillie) was going to the area to meet a woman and "they were possibly going to meet up for a date," the report states. The investigation showed there was a target for the homicide and the victim was shot "due to ongoing gang beef and issues," the report states.
Mills told detectives the victim "had $20,000 on his head," which means whoever kills the victim will receive $20,000 payment. Mills says he got paid $10,000 for murder because he had to split it with the second shooter, the report states.
The arrest report says the second suspect is known to law enforcement and is outstanding.
A cellphone at the scene was taken to the JSO Computer Forensics Unit and downloaded. The arrest report says it was found that the victim was calling and messaging a person on Instagram and his cell phone traced it back to Diamond Harris.
During Harris’ interview with detectives, the arrest report says Harris admitted to speaking with the victim through Instagram, voice calls, and text messages.
Harris told detectives she denied providing the victim with the incident location and speaking with him around the time of the murder. However, the report says the victim’s cell phone revealed evidence that did not match what Harris said and she was in contact with Harris until his death.
The report says Harris used her phone to contact her boyfriend, Ju’Quan Mills, when she got off the phone with the victim around the time of the murders. Harris denied any involvement with the victim’s death.
On Harris’ phone, detectives found several text threads between Harris and Mills discussing what Harris should message the victim to "keep him interested in seeing her and to presumably lure him to her location," the report states.
Content on Harris’ phone also shows she and Mills were still dating and he was helping her with what to say to the victim.
The arrest report says data from Mills' phone found he was at the scene at the time of the homicide.
During Mills’ interview with detectives, the report says he initially denied all involvement with the murder of the victims and said he was at a 24-hour laundry mat hanging out with a friend.
Mills eventually signed consent for detectives to view his cell phone and showed detectives his recently deleted conversations. Mills says he "used his baby mama’s Instagram account and pretended to be her to message and speak to the victim," the report states. Mills admitted to shooting the victims along with another suspect.
Harris' bond was $250,003. Mills’ bond was $750,000. Both are currently not in jail, are on house arrest, and are represented by public defenders, according to court documents.
First Coast News reached out to both families of the victims and was told JSO has not informed them of the arrests of the suspects accused of killing their loved ones.
